The terminal device in the embodiment of the present invention may be a terminal device having an operating system. The operating system may be an Android (Android) operating system, an ios operating system, or other possible operating systems, and embodiments of the present invention are not limited in particular.
Next, a software environment applied to the method for reducing charging interference according to the embodiment of the present invention is described by taking an android operating system as an example.
Fig. 1 is a schematic diagram of an architecture of a possible android operating system according to an embodiment of the present invention. In fig. 1, the architecture of the android operating system includes 4 layers, which are respectively: an application layer, an application framework layer, a system runtime layer, and a kernel layer (specifically, a Linux kernel layer).
The application program layer comprises various application programs (including system application programs and third-party application programs) in an android operating system.
The application framework layer is a framework of the application, and a developer can develop some applications based on the application framework layer under the condition of complying with the development principle of the framework of the application.
The system runtime layer includes libraries (also called system libraries) and android operating system runtime environments. The library mainly provides various resources required by the android operating system.

Taking an android operating system as an example, in the embodiment of the present invention, a developer may develop a software program for implementing the method for reducing charging interference provided in the embodiment of the present invention based on the system architecture of the android operating system shown in fig. 1, so that the method for reducing charging interference may operate based on the android operating system shown in fig. 1. Namely, the processor or the terminal device can implement the method for reducing charging interference provided by the embodiment of the invention by running the software program in the android operating system.
The terminal device in the embodiment of the invention can be a mobile terminal device and can also be a non-mobile terminal device. For example, the mobile terminal device may be a mobile phone, a tablet computer, a notebook computer, a palm computer, a vehicle-mounted terminal device, a wearable device, an ultra-mobile personal computer (UMPC), a netbook or a Personal Digital Assistant (PDA), and the like, and the non-mobile terminal device may be a Personal Computer (PC), a Television (TV), a teller machine or a self-service machine, and the like, and the embodiment of the present invention is not particularly limited.
The execution subject of the method for reducing charging interference provided in the embodiment of the present invention may be the terminal device, or may also be a functional module and/or a functional entity capable of implementing the method for reducing charging interference in the terminal device, which may be specifically determined according to actual use requirements, and the embodiment of the present invention is not limited. The following takes a terminal device as an example to exemplarily describe the method for reducing charging interference according to the embodiment of the present invention.
As shown in fig. 2, an embodiment of the present invention provides a method for reducing charging interference, which may include steps 10 to 13 described below.
Step 10, the terminal device obtains a first charging current value of the terminal device.
Optionally, in the embodiment of the present invention, the terminal device may be in a power-on state.
When the terminal equipment is in the starting state, the terminal equipment can communicate with the base station. At this time, if the terminal device in the power-on state is charged, the communication quality of the terminal device may be degraded due to the noise generated from the terminal device. Therefore, in the embodiment of the invention, when the terminal device in the power-on state is charged, the terminal device can obtain the first charging current value of the terminal device.
Optionally, in this embodiment of the present invention, the first charging current value may be a current value currently charging the terminal device. For example, the first charging current value may be 2A (amperes), 1.8A, or 1.5A.
And step 11, the terminal equipment determines a target frequency band from at least one frequency band stored in the terminal equipment according to the first charging current value.
And under the condition of one charging current value, each frequency band in at least one frequency band corresponds to one communication parameter value respectively. The target frequency band is a frequency band corresponding to the minimum communication parameter value in at least one frequency band under the target charging current value. The target charging current value is less than or equal to the first charging current value.
In the embodiment of the present invention, at least one frequency band stored in the terminal device may be a frequency band available to the terminal device; i.e. the at least one frequency band may be a frequency band in which the terminal device is allowed to register. Specifically, when the terminal device enters the coverage of a network, if the terminal device is not registered in the network, the terminal device registers in the network. In the process of registering the terminal device in the network, the terminal device may first detect a frequency band supported by the network, determine the frequency band supported by the network as a frequency band available to the terminal device, that is, a frequency band allowed to be registered by the terminal device, and then select a frequency band (for example, a frequency band with a signal strength greater than or equal to a preset threshold) from the frequency bands for registration.
In the embodiment of the present invention, a plurality of corresponding relationships may be preset in the terminal device, where each corresponding relationship is a corresponding relationship between one charging current value, a plurality of frequency bands, and a plurality of communication parameter values corresponding to the plurality of frequency bands (where one frequency band corresponds to one communication parameter value). After the terminal device obtains the charging current value of the terminal device (i.e., the first charging current value) and the frequency band (i.e., the at least one frequency band) allowed to be registered by the terminal device in the network in which the terminal device resides, the terminal device may determine, according to the first charging current value, the at least one frequency band, and the plurality of correspondence relationships, a minimum communication parameter value from communication parameter values corresponding to the at least one frequency band at a target charging current value (the target charging current value is less than or equal to the first charging current value), and then determine the frequency band corresponding to the minimum communication parameter value as the target frequency band.
The plurality of corresponding relations may be preset in the terminal device for a manufacturer of the terminal device. The plurality of frequency bands in the plurality of correspondence relationships preset in the terminal device may be all frequency bands available to the terminal device on the spectrum resource. The frequency bands can belong to the same network standard, can belong to different network standards, can belong to the same country region, can belong to different country regions, can belong to the same operator, and can belong to different operators. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.
For example, in the embodiment of the present invention, taking the network standard as an example, the network standard may be a TDMA network standard, a CDMA network standard, or a Long Term Evolution (LTE) network standard. Of course, the network standard may also be other possible network standards, and may be determined specifically according to actual use requirements, and the embodiment of the present invention is not limited.
Of course, it can be understood that, in the embodiment of the present invention, after a manufacturer of a terminal device presets all frequency bands available to the terminal device on a spectrum resource in the terminal device, the manufacturer of the terminal device may also update the frequency bands according to changes of the frequency bands on the spectrum resource in a user use process.
Optionally, in this embodiment of the present invention, the communication parameter value may include at least one of a reception sensitivity value, an interference strength value, a packet loss rate value, and a delay value. The interference strength value can be used for reflecting the interference strength, and the smaller the interference strength value is, the lower the interference strength is; the receiving sensitivity value can be used for reflecting the receiving sensitivity, and the smaller the receiving sensitivity value is, the higher the receiving sensitivity is, and the stronger the capability of the receiving end for receiving weak signals is; the packet loss rate value can be used for reflecting the packet loss rate, and the smaller the packet loss rate value is, the better the quality of the communication channel is; the delay value may be used to reflect the delay, and the smaller the delay value, the better the quality of the communication channel. Of course, the communication parameter value may also include a possible parameter value in other communication processes, which may be determined specifically according to actual usage requirements, and the embodiment of the present invention is not limited.
In a general situation, because communication parameter values corresponding to different frequency bands are different at one charging current value (for example, at one charging current value, interference strength corresponding to a low frequency band is high, and interference strength corresponding to a high frequency band is low), when a communication parameter value is at least one of a reception sensitivity value, an interference strength value, a packet loss rate value, and a time delay value, the terminal device determines, according to a plurality of correspondence relationships stored in the terminal device, a communication parameter value corresponding to each frequency band in at least one frequency band at one charging current value, and determines a frequency band that can optimize communication quality of the terminal device. For example, under the target charging current value, the terminal device may determine, according to the interference strength value corresponding to each frequency band of the at least one frequency band, a frequency band with the minimum interference to the terminal device in the at least one frequency band, and when the terminal device is registered to the frequency band with the minimum communication parameter value, the communication quality of the terminal device under the target charging current value may be improved.
For example, the at least one frequency band saved in the terminal device (i.e., the frequency band available to the terminal device or the frequency band allowed to be registered by the terminal device) may include a first frequency band, a second frequency band, and a third frequency band, and each of the at least one frequency band may include an uplink frequency band and a downlink frequency band. The uplink frequency band of the first frequency band may be 699M-716M, and the downlink frequency band of the first frequency band may be 729M-746M; the uplink frequency band of the second frequency band may be 832M-862M, and the downlink frequency band of the second frequency band may be 791M-821M; the uplink frequency band of the third frequency band may be 824M-849M, and the downlink frequency band of the third frequency band may be 869M-894M.
Optionally, in the embodiment of the present invention, under different charging current values, communication parameter values corresponding to the same frequency band may be the same or different. For example, assuming that the charging current value is 2A, 1.8A or 1.5A, and the communication parameter value is an interference strength value, when the charging current value is 2A, the interference strength value corresponding to the first frequency band of the at least one frequency band may be 10dB (decibel); when the charging current value is 1.8A, the interference intensity value corresponding to the first frequency band of the at least one frequency band may be 8 dB. When the charging current value is 1.5A, the interference intensity value corresponding to the first frequency band of the at least one frequency band may be 6 dB. For another example, if the charging current value is 2A, 1.8A or 1.5A, and the communication parameter value is a receiving sensitivity value, the receiving sensitivity value corresponding to the first frequency band may be-95 dBm (decibel-milliwatt) when the charging current value is 2A; when the charging current value is 1.8A, the receiving sensitivity value corresponding to the first frequency band may be-98 dBm. When the charging current value is 1.5A, the receiving sensitivity value corresponding to the first frequency band may be-101 dBm.
Alternatively, in the embodiment of the present invention, the target charging current value may be the first charging current value, or may be another charging current value (for example, may be a second charging current value described in the following embodiment, where the second charging current value is smaller than or equal to the first charging current value). The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.
Optionally, in the embodiment of the present invention, one possible implementation manner (referred to as manner one) is that the terminal device may first obtain a first communication parameter value corresponding to each frequency band at the first charging current value; and then, directly taking the frequency band corresponding to the minimum first communication parameter value in at least one frequency band under the first charging current value as a target frequency band.
Another possible implementation manner (referred to as a manner two) is that the terminal device may first obtain a first communication parameter value corresponding to each frequency band at the first charging current value; judging whether the minimum first communication parameter value is smaller than or equal to a preset threshold value or not; under the condition that the minimum first communication parameter value is smaller than or equal to a preset threshold value, the terminal equipment determines a frequency band corresponding to the minimum first communication parameter value in at least one frequency band as a target frequency band; or under the condition that the minimum first communication parameter value is greater than the preset threshold, the terminal device determines the frequency band corresponding to the minimum second communication parameter value in at least one frequency band as the target frequency band under the second charging current value (the second charging current value is less than or equal to the first charging current value). For the above two possible implementations, detailed descriptions will be given in the following embodiments, which are not repeated herein.
And step 12, the terminal equipment judges whether the target frequency band is the same as the frequency band registered by the terminal equipment.
In this embodiment of the present invention, in a case that the target frequency band is different from the frequency band registered by the terminal device, the terminal device may continue to perform step 13 described below. And under the condition that the target frequency band is the same as the frequency band registered by the terminal device, because the frequency band registered by the terminal device is the frequency band with the minimum communication parameter value under the target charging current value, namely the frequency band registered by the terminal device is the frequency band with the optimal communication quality of the terminal device, the terminal device does not need to switch the registered frequency band.
And step 13, under the condition that the target frequency band is different from the frequency band registered by the terminal equipment, the terminal equipment switches the frequency band registered by the terminal equipment into the target frequency band.
Optionally, in this embodiment of the present invention, the method for switching the frequency band registered by the terminal device to the target frequency band by the terminal device may include: the terminal device registers from the frequency band registered by the terminal device, and then registers to the target frequency band. For a specific description of de-registration and registration, reference may be made to the related art, and details of embodiments of the present invention are not repeated.
The embodiment of the present invention provides a method for reducing charging interference, where a frequency band (i.e., a target frequency band) corresponding to a minimum communication parameter value in at least one frequency band stored in a terminal device at a target charging current value is determined from the at least one frequency band stored in the terminal device according to a first charging current value of the terminal device, and when the target frequency band is different from the frequency band registered by the terminal device, a frequency band registered by the terminal device may be switched to the target frequency band, and the frequency band corresponding to the minimum communication parameter value is generally a frequency band with the best communication quality of the terminal device.
In a possible implementation manner of the embodiment of the present invention (i.e., the first implementation manner), as shown in fig. 3 with reference to fig. 2, the step 11 can be specifically implemented by the following step 110-111.
Step 110, the terminal device obtains a first communication parameter value corresponding to each frequency band under the first charging current value.
And step 111, the terminal device determines a frequency band corresponding to the minimum first communication parameter value in the at least one frequency band as a target frequency band.
Wherein, in this implementation, the target charging current value is the first charging current value.
For the description of the first charging current value and the at least one frequency band, reference may be made to the description of the first charging current value and the at least one frequency band in the foregoing embodiments, and details are not repeated here.
In this embodiment of the present invention, the terminal device may first obtain the first communication parameter value corresponding to each frequency band at the first charging current value, and then determine the frequency band corresponding to the minimum first communication parameter value (i.e., the above-mentioned target frequency band) from at least one frequency band stored in the terminal device. In this implementation, the target charging current value is the first charging current value.
A method for determining a target frequency band from at least one frequency band by a terminal device according to a first charging current value according to an embodiment of the present invention is exemplarily described below with reference to table 1 and table 2.
For example, as shown in table 1, assuming that the charging current values are 2A, 1.8A and 1.5A, respectively, and at least one frequency band (i.e., a frequency band available for the terminal device or a frequency band allowing the terminal device to register) includes a first frequency band, a second frequency band and a third frequency band, table 1 shows a corresponding relationship between the charging current values, the frequency bands and the interference strength values in the terminal device according to an embodiment of the present invention.
TABLE 1
Value of charging current First frequency band Second frequency band Third frequency band
2A 10dB 8dB 6dB
1.8A 8dB 6dB 3dB
1.5A 6dB 4dB 2dB
Referring to table 1, the terminal device may first obtain that the first charging current value is 2A, and may obtain that, when the first charging current value is 2A, the interference intensity value corresponding to the first frequency band is 10dB, the interference intensity value corresponding to the second frequency band is 8dB, and the interference intensity value corresponding to the third frequency band is 6dB, and since the frequency band corresponding to the minimum interference intensity value of 6dB is the third frequency band, the terminal device may determine the third frequency band of the three frequency bands as the target frequency band, that is, the terminal device may determine the frequency band corresponding to the minimum first communication parameter value (for example, the minimum interference intensity value) in at least one frequency band as the target frequency band.
For another example, as shown in table 2, still assuming that the charging current values are 2A, 1.8A and 1.5A, respectively, and at least one frequency band (i.e., a frequency band available for the terminal device or a frequency band allowing the terminal device to register) includes a first frequency band, a second frequency band and a third frequency band, then table 2 shows a corresponding relationship between the charging current values, the frequency bands and the receiving sensitivity values in the terminal device according to the embodiment of the present invention.
TABLE 2
Value of charging current First frequency band Second frequency band Third frequency band
2A -95dBm -98dBm -101dBm

Since the communication parameter value of the target frequency band is the smallest, and the frequency band corresponding to the smallest communication parameter value is generally the frequency band with the best communication quality of the terminal device, the communication quality of the terminal device at the target charging current value can be improved by registering the terminal device to the frequency band with the smallest communication parameter value in the embodiment of the present invention.

And step 115, under the condition that the minimum first communication parameter value is larger than the preset threshold value, the terminal device determines the frequency band corresponding to the minimum second communication parameter value in at least one frequency band under the second charging current value as the target frequency band.
Wherein the second charging current value is smaller than the first charging current value, the minimum second communication parameter value is smaller than or equal to a preset threshold value, and in this case, the target charging current value is the second charging current value.
Optionally, in this embodiment of the present invention, before the terminal device determines, at the second charging current value in step 115, a frequency band corresponding to a minimum second communication parameter value in at least one frequency band as the target frequency band, the method provided in this embodiment of the present invention may further include the following step 115 a.
And step 115a, under the condition that the minimum first communication parameter value is larger than a preset threshold value, the terminal equipment is charged according to a second charging current value.
Optionally, in the embodiment of the present invention, the preset threshold may be obtained according to actual experience and a communication parameter value, and the embodiment of the present invention is not limited specifically.
For example, when the communication parameter value is the interference strength value, the preset threshold may be a preset threshold of the interference strength, for example, the preset threshold may be 5 dB; when the communication parameter value is a reception sensitivity value, the preset threshold may be a preset threshold of the reception sensitivity value, for example, the preset threshold may be-100 dBm. Of course, the preset threshold may also be other possible preset thresholds, which may be determined according to actual usage requirements, and the embodiment of the present invention is not limited.
For the description of the first charging current value and the at least one frequency band, reference may be made to the description of the first charging current value and the at least one frequency band in the foregoing embodiments, and details are not repeated here.
It can be understood that, in the embodiment of the present invention, the first communication parameter value is a communication parameter value corresponding to each frequency band in at least one frequency band (that is, a frequency band in which the terminal device is allowed to register) at the first charging current value; and the second communication parameter value is a communication parameter value corresponding to each frequency band in at least one frequency band under the second charging current value.
In the embodiment of the present invention, the terminal device may first obtain, according to the first charging current value, a first communication parameter value corresponding to each frequency band at the first charging current value. Then, the terminal device may determine whether the minimum first communication parameter value is less than or equal to a preset threshold value. When the minimum first communication parameter value is less than or equal to the preset threshold value, the terminal device may use the first charging current value as a target charging current value, and determine, in at least one frequency band at the first charging current value, a frequency band corresponding to the minimum first communication parameter value as a target frequency band; and when the minimum first communication parameter value is greater than the preset threshold, the terminal device may use the second charging current value as the target charging current value, and determine, in the second charging current value and at least one frequency band, a frequency band corresponding to the minimum second communication parameter value as the target frequency band.
Still taking table 1 and table 2 in steps 110 to 111 as an example, a method for determining, by the terminal device, the target frequency band from the at least one frequency band stored in the terminal device according to the first charging current value will be exemplarily described below.
For table 1, it is assumed that the charging current values are 2A, 1.8A and 1.5A, respectively, at least one frequency band (i.e., a frequency band available for the terminal device or a frequency band allowing the terminal device to register) includes a first frequency band, a second frequency band and a third frequency band, the communication parameter value is an interference strength value, and the preset threshold value is 5 dB. The terminal device may first obtain the first charging current value as 2A, and may obtain the interference strength value corresponding to the first frequency band as 10dB, the interference strength value corresponding to the second frequency band as 8dB, and the interference strength value corresponding to the third frequency band as 6dB when the first charging current value is 2A, and determine that the minimum interference strength value (hereinafter, referred to as a minimum first interference strength value) is 6 dB. Since the minimum first interference intensity value (i.e., 6dB) is greater than the preset threshold value (i.e., 5dB), when the charging current value is 1.8A, the terminal device may obtain an interference intensity value corresponding to the first frequency band as 8dB, an interference intensity value corresponding to the second frequency band as 6dB, and an interference intensity value corresponding to the third frequency band as 3dB, and determine the minimum interference intensity value (hereinafter referred to as a minimum second interference intensity value). Is 3 dB. Since the minimum second interference intensity value (i.e., 3dB) is smaller than the preset threshold value (i.e., 5dB), the terminal device may use the third frequency band corresponding to the minimum second interference intensity value (i.e., 3dB) at 1.8A (i.e., the second charging current value) as the target frequency band. That is, under the condition that the minimum first communication parameter value is greater than the preset threshold, the terminal device may determine, as the target frequency band, a frequency band corresponding to the minimum second communication parameter value in at least one frequency band at the second charging current value (i.e., the target charging current value).
For table 2, it is assumed that the charging current values are 2A, 1.8A and 1.5A, respectively, at least one frequency band (i.e., a frequency band available for the terminal device or a frequency band allowing the terminal device to register) includes a first frequency band, a second frequency band and a third frequency band, the communication parameter value is a reception sensitivity value, and the preset threshold value is-100 dBm. The terminal device may first obtain that the first charging current value is 2A, and may obtain that, when the first charging current value is 2A, the reception sensitivity value corresponding to the first frequency band is-95 dB, the reception sensitivity value corresponding to the second frequency band is-98 dB, and the reception sensitivity value corresponding to the third frequency band is-101 dB, and determine that the minimum reception sensitivity value (hereinafter, referred to as the minimum first reception sensitivity value) is-101 dB. Since the minimum first receiving sensitivity value (i.e., -101dB) is smaller than the preset threshold value (i.e., -100dBm), the terminal device may use the third frequency band corresponding to the minimum first receiving sensitivity value (i.e., -101dBm) at the first charging current value as the target frequency band. That is, in a case that the minimum first communication parameter value is less than or equal to the preset threshold, the terminal device may determine, as the target frequency band, a frequency band corresponding to the minimum first communication parameter value in at least one frequency band at the first charging current value (i.e., the target charging current value).
The embodiment of the invention provides a method for reducing charging interference, which can not only meet the condition that a communication parameter value (for example, the communication parameter value can be an interference intensity value or a receiving sensitivity value) corresponding to a target frequency band is smaller than a preset threshold value, but also meet the condition that the communication parameter value corresponding to the target frequency band is minimum under a target charging current value. Therefore, the communication parameter value corresponding to the target frequency band is the minimum communication parameter value in the communication parameter values smaller than the preset threshold value, so that the communication quality of the terminal equipment at the target charging current value can be further improved.
Alternatively, in the embodiment of the present invention, the step 11 may be specifically implemented by the following steps 116 to 117.
Step 116, the terminal device determines whether the first charging current value is greater than or equal to a preset current value.
And step 117, when the first charging current value is greater than or equal to the preset current value, the terminal device determines a target frequency band from at least one frequency band stored in the terminal device.
For the description of the first charging current value and the at least one frequency band, reference may be made to the description of the first charging current value and the at least one frequency band in the foregoing embodiments, and details are not repeated here.
For example, in the embodiment of the present invention, the preset current value may be 1A.
The embodiment of the invention provides a method for reducing charging interference, which can be used for firstly obtaining a first charging current value of terminal equipment and judging whether the first charging current value is greater than or equal to a preset current value or not. In this way, the terminal device may obtain at least one frequency band only when the first charging current value is greater than or equal to the preset current value, and continue the relevant steps in the above embodiment, otherwise, the terminal device may not need to execute the relevant steps in the above embodiment, and thus, power consumption of the terminal device may be reduced.
